I’m order to find the missing amount, you need to subtract 343 from 979
979-343= 636
You can always check your work by plugging in your answer. For example:
343+636=979 which is true

Okay basically just subtract 343 from 979. You do this because if you have the sum already, you need to use another operation to find the missing number in the equation, this case, subtraction. This will give you 636. You can check by applying 636 into the equation. 343 + 636= 979.
